- react 18.2.0 to 19.2.6
- react-dom 18.2.0 to 19.2.6
- @types/react 18.2.39 to 19.2.15
- @types/react-dom 18.2.17 to 19.2.3
React 19 breaking changes fixed:
- useRef<T>(null) now returns RefObject<T | null>; cast to
RefObject<T> at 16 component call sites (safe, runtime unchanged)
- useRef<T>() without arg no longer valid; add | undefined>(undefined)
in useDebounce, useFileDrop, useThrottle, useVirtualPaginator hooks,
RoomInput, RoomTimeline, and ClientNonUIFeatures
- useReducer<typeof reducer> 1-arg form removed; drop explicit type arg
in useForceUpdate (inferred from reducer function)
- global JSX namespace removed; import type { JSX } from react in
react-custom-html-parser.tsx
